Resonator delete for 162 TSI R-line?

[Exxie]

I think the car is too noisy internally now (engine noise) so I will pass on making it any noisier. It disappoints me they did not put more effort into reducing the engine noise when the motor is working a bit hard.

Anyway, early impressions are similar to Shock's - only slightly louder, but a much deeper, more pleasing (to my ears at least) note.

Unfortunately, no more pops and crackles on upshift, but the car is only 700km old so I'm hoping this will develop.

It is amazing to read how some people trying to make same car to be louder than more quite and on other side others as myself how to make it less noise and to reduce engine noise ,cabin noise ,tyre noise etc ... he he

Actually the Golf GTI &R have sound deadening and then have an artificial device to make engine noises.

A lot of higher end brands are doing it. You want to eliminate the road noise and enhance the engine/exhaust note.

Hi
Is that VW/ Audi hardware thing called ''soundaktor''. Recently when was under car I noticed on my Q3 when comparing to Tiguan Muffler exhaust pipe on q3 has extra some wiring and solenoids going inside Muffler I don't know exactly what Is purpose? maybe to control reduce open/close inside pipe size and control in sound change or pure performance related ? Is this thing maybe responsible why Audi q3 is so quit when engine is running on idle, sometime make me think is engine off and put smile on my face.I am wondering if yes if is than any way possible to retrofit tweak similar on Tiguan to make it really quite running as Q3 engine .

That will probably be a butterfly valve to close up one of the sides from the middle box. This will make it quieter but also increase back pressure sightly, which can help to warm the catalytic converter more quickly during a cold start.

Thx Exxie for explanation , if this will make it quieter I would be always happy to make mod and retrofit on my Tiguan anything will make it quitter , however wondering if Highline or R-line Tiguan 2 have this hardware thing already built in? my 132 Comfortline don't, the second if possible to retrofit which module control this thing and where wiring is connected to?
One more question why my Tiguan every time when motor had rest and is cool down ( usually If not driven overnight ) when I start it I hear some very noise loud sound like some sort of high power high pressure pump and burning engine sound, it take like 20 sec. each time on cold than stop disconnect back to normal ? Thx

I wouldn't bother retrofitting an active valve system to make the exhaust quieter (they're generally on sports exhausts that are much louder, so they need a quiet mode). If you want to muffle your exhaust more, you could possibly add some material to your existing muffler. Speak to an exhaust shop.

Having said that, I doubt that the exhaust of a 132tsi makes much noise. It's more likely to be engine noise entering the cabin.

Might be the oil pump or something like that, probably nothing to worry about. If you're concerned, ask the dealership.

Very much so. My car spends a lot of time at 110 to 120 and climbing long hills and the motor is noisier than I like. In the metro area the few times I am there no problems at all. I have the Golf PP if I want something that makes a noise and goes harder.

Just a small update for anyone interested.

Initially, the resonator delete was subtle, but as I've done more KMs, it's gotten progressively louder. There are indeed little farts on upshift, but only when shifting from high-ish revs and at least 50% throttle.

I'm hoping it continues to develop on this trajectory. I won't be touching the muffler. Downpipe and tune will come in time and this should bring a lot more noise as well. Would be good to hear from the initial OP (Shock) re the Unitronic flash.

Thx Exxie for explanation , will not than touch it than . You and Ozsko are right , motor noise and engine noise is coming from engine bay , I try to put some sound acoustic 1cm thick sheet used for roof insulation and it make bit difference, however this is only provisional for demo will need proper job . Reason for Engine to be noise on 2.0L compared to 1.4 which is very very low noise same as Q3 , , is 2.0L use chain and 1.4 use timing belt which I much more prefer , easy to replace yourself less noise and vibration, don't see reason VW to use troublesome chain . New audi Q5( also upcoming 1.5 VW engine) use now timing belt according to video reviews and was noted that all new VW and AUDI engine will return back to timing belt on upcoming cars. Today quality timing belts can go over 200000km easy, but chain knowing VW Golf V GT can start problems as early wearing at 40k-60k km, hope Tiguan will not have this issue with early chain wear , whish they used timing belt instead ;(

Hi cameleon72. You may be right about the noise when using a timing chain vs a belt. BUT a timing chain is far more reliable. I owned a 1992 Mitsubishi VR4 which used a timing belt. I had the car regularly serviced by the Mitsubishi dealer. The belt was due for replacement at 100,000 km. The car had its 80k service and 2.5 k later the timing belt broke and my engine was turned into a very expensive door stop. $7,000 later it was back on the road. This was 1998 money. So I am actually very happy to have a timing chain installed. If I wanted a super quiet car I would not have bought my 162 tsi Tiguan. I am so very happy with this car. It gives me so much better "bang for buck" than any other car on the Australian market. Happy motoring.

Also when a timing chain wears it gets noisy first. So plenty of warning. When a timing belt wears it just breaks. No warning.

Any chance of you posting a soundbite/video? Easy to upload one to youtube straight from a mobile phone.

Fairly interested in doing something similar to mine,

I've tried, but all you can hear is wind noise. If I manage to get a half decent one, I'll post it.

Ahh ok, thanks
